To all whom it may concern:

Be it known that I, J oH'N LARDOS, a subject of Greece, residing at Akron, in the county of Summ1t and State of Oh1o,have

invented new and useful Improvements in Vehicle-Wheel Tlres, of which the following is aspec1ficat1on.

This invention relates to a detachable cov ering, sheath or envelop for elastic tires and hereinafter specifically described and illusis primarily designed for use in connection with pneumatic tires. 7

The object of the invention is to provide a sheath or covering which may be placed over the tire for protecting'the same against puncture and w'hichis provided with means to prevent skidding and also to-increase the tractive'properties of the tire when the covering is in place thereon.

With the foregoing "and other objects in .VlQW, the invention consists in the novel construction, combination and arrangement of" parts constltutlng the invention to be trated' in the accompanying drawings which form-a part hereof wherein is shown the preferred embodiment of the invention, but

improved covering in operative relation it istolbe understood that changes, variationsand modifications can be resorted to which come within the scope of the matter hereinafter claimed.

In the drawings in which similar reference numerals indicate like parts in the different figures,

F igure l is a transverse sectional view of the rim portion of a vehicle wheel, showing a pneumatic tire mounted thereon and my with respect to the tire, the section being taken approximately on line 1 of Fig. 1

- Fig. 2 is .a fragmentary sectional view of the deviceshown in Fig. 1 taken approxi mately on line 2 of Fig. 4.

I S v F1g. 3 1s a longitudinal sectlonal v1ew ot a portion of the device shown in Fig. 1 taken approximately on line 3 f Fig. 2, and Fig; 4 is a. plan view of a portion of the device shown inJFig. 1 with portions thereof broken away'to better illustrate the same.

Referring to the drawings in detail the reference numeral 1 denotes a vehiclerim provided with an offset 2 at one side and containing a circumferential channel in which is seated a tire retaining ring3, the tire rim being of conventional form. Mounted on therim is a pneumatic tire 4c.

The device which forms the subject mat- Specification of Letters Patent.

ter of the present invention comprises a sheath, covering or envelop which is arranged to be positloned around the tire l and protect the same and to increase the tractive qualities thereof and also to prevent skidding of the car when the device is in use. The invention embodies a layer 5 which entirelyenvelops the tire 4 and with the inner separated edges thereof secured under the'bead portion 6 of the tire and held in place by said head when the tire is inflated and preferably secured on the opposite side under the'locking ring 3 as shown in F l. The outer tread forming portion of the member 5 is covered by a layer 7 of foraminous or reticulated material such as 7 wire cloth 7 which is preferablyvulcanized to the layer 5 during the building up of the device. 'Mounted on the layer 5 and covermg the layer 7 1s a strip 8 of rubber, preferably crescent-shapedin cross section and provided with a series of regularly recurringprojections 9, these projections being in the form of ribs for addin g to the tractive properties of the tire and as they are arrangedin spaced relation the spaces between'them afford means for entrance of the material of the roadway and also to prevent skidding of the same. The side portions of the member 8 are gradually sloped down or inclined andare secured by vulcanization to the member 5 covering the lateral portions of the layer 7 thereby securing the layer 7 in position and preventing exposure of the same to the elements. The joints between the lateral portions of the member 8 and the member 5 are covered by circumferentially extending strips 10 preferably formed of rubber saturated fabric which when the entire device is vulcanized unite with the members 8 and 5 to form the entire device into a unitary product. By the use of this device the entire tire is protected against injury and inreased tractive qualities are developed and at the same time the vehicle on which a tire skid due to the transverse ribs 9. The layer 7 7 of foraminous or reticulated material ascluding a fabric sheath anchored adjacent ing for inclosing' a tire, said covering inequipped with this device is less likely to the tire heads, a'layer of reticulated mate rial applied over the tread portion of the sheath and vulcanized thereto, a strip of rubber crescent-shaped in cross-section rial and circuniferentially extending strips 10 vulcanized to the opposite edges of the crescent shaped rubber strip and-the fabric sheath and overlying the side edges of the strip of rubber. V a V In testimony whereof I have hereunto set my hand.
